To prevent damage to property and injury to the user, the icons shown below will be used to warn of varying 

levels of danger.

Every indication is critical to the safe operation of the Water Heater and must be understood and observed.

Potential dangers from accidents during installation and use are divided into the following four categories. 

Closely observe these warnings; they are critical to your safety.

Important Safety Information

Icons warning of risk level

This is the safety alert symbol. It is used to alert you to potential personal injury hazards. 

Obey all safety messages that follow this symbol to avoid possible injury or death.

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death 

or serious injury.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death 

or serious injury.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in minor 

or moderate injury.

NOTICE

Indicates a potentially hazardous situation which, if not avoided, may result in 

property damage.

Vapors from flammable liquids will explode 

and catch fire causing death or severe burns.

Do not use or store flammable products such 

as gasoline, solvents or adhesives in the same 

room or area near the Water Heater.

Keep flammable products:

  1. Far away from the Water Heater.

  2. In approved containers.

  3. Tightly closed.

  4. Out of children’s reach.

Vapors:

  1. Cannot be seen.

  2. Vapors are heavier than air.

  3. Go a long way on the floor.

  4.  Can be carried from other rooms to the 

main burner by air currents.

After the Water Heater has been out of use 

for a long time make sure that you fill the 

condensate trap with water.

This is to prevent dangerous exhaust gases 

from entering the building.

Failure to fill the condensate trap could result 

in severe personal injury or death.

(Refer to page 14 for further instructions.)

DANGER

Hot Water Heater temperatures over 125°F 

(52°C) can cause severe burns instantly or 

death from scalding.

Children, disabled and elderly are at the highest 

risk of being scalded. 

Feel water temperature 

before bathing or showering. 

Temperature limiting valves 

are available, consult with 

installer.

Do not use the Water Heater if the intake/

exhaust pipe is displaced, has holes, is clogged 

or is corroded.
This will cause carbon monoxide poisoning 

and a potential fire hazard.
Do not allow anyone to change the water 

temperature while hot water is being used.

To prevent scalding, do not change the water 

temperature to a higher setting.

[When supplying combustion air from the 

indoors]

Check whether or not the air supply vent is 

blocked with dust, trash, a towel, or the like.

Blocking the opening may result in incomplete 

combustion.
